Abstract
The utility model relates to the technical field of a main shaft on a machine bed, in particular to a main shaft tail floating holder. The main shaft tail floating holder structure comprises a main shaft, a bearing and a holder, the periphery of the main shaft tail is connected with the bearing, the upper part of the bearing is provided with an inner sleeve and an outer sleeve, the holder is arranged between the inner sleeve and the outer sleeve, one end of the bearing is provided with a baffle ring, a locking nut supports the baffle ring, and the bearing is connected with the holder by a flange. By the adoption of the main shaft tail floating holder structure, deformation caused by thermal expansion of the main shaft is released, so the operation of a main transmission and the main shaft is stable and reliable.
Description
Technical field
The utility model relates to the machine tool chief axis technical field, especially a kind of main shaft afterbody retainer structure of floating.
Background technology
Be to adapt to the thick fine finishining of part, range of spindle speeds is more and more wideer, and speed is increasingly high, and main shaft bearing caloric value when high speed is huge, is out of shape inconsistently, is prone to kill and burns bearing.
The utility model content
In order to overcome the deficiency of prior art, the utility model provides a kind of main shaft afterbody retainer structure of floating.
The utility model solves the technical scheme that its technical problem adopted: a kind of main shaft afterbody retainer structure of floating; Comprise main shaft, bearing, retainer, be connected with bearing around the main shaft afterbody, cover and overcoat in the bearing top is equipped with; Between interior cover and the overcoat retainer is housed; Bearing one end is provided with back-up ring, and locking nut is supporting back-up ring, is provided with flange between bearing and the retainer and is connected.
The beneficial effect of the utility model is that the main shaft afterbody adopts the retainer structure of floating, and discharges the distortion of main shaft thermal stretching, guarantees the reliable and stable of main transmission and spindle operation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of the utility model;
Among the figure 1, main shaft, 2, bearing, 3, retainer, 4, interior cover, 5, overcoat, 6, back-up ring, 7, locking nut, 8, flange.
The specific embodiment
Like Fig. 1 is the structural representation of the utility model, and a kind of main shaft afterbody retainer structure of floating comprises main shaft 1, bearing 2, retainer 3; Be connected with bearing 2 around main shaft 1 afterbody; Cover 4 and overcoat 5 were equipped with retainer 3 between interior cover 4 and the overcoat 5 in bearing 2 tops were equipped with, and bearing 2 one ends are provided with back-up ring 6; Locking nut 7 is supporting back-up ring 6, and bearing 2 is provided with flange 8 with retainer 3 and is connected.
When the bearing portions of former main shaft afterbody separates, adopt thermal deformation that above-mentioned unsteady retainer structure makes main shaft and bearing in axial release, guaranteed to run up for a long time not locking.
